GuardedBox

GuardedBox is a platform for storing and sharing sensitive information such as credentials, digital certificates, and documents. It is positioned as an alternative to traditional collaborative password managers, offering end-to-end encryption with a unique encryption key for each secret and group, and applying zero-knowledge and zero-trust principles. The platform is certified under post-quantum cryptography standards referenced by CCN-CERT and NIST. It can be deployed on-premise or as a cloud SaaS, in public, private, or public-for-private configurations, allowing organizations to retain control over their data location and management. Key features include cryptographic signature-based login to prevent impersonation, client-side identity verification of contacts, individual and group secret sharing with configurable permissions, ephemeral read-only or editable links for sharing with external parties who do not hold an account, customisable templates for standardising secret formats, and an immutable audit trail that records application and user events in a centralised blockchain-based log without revealing sensitive content. The system also provides notifications, reminders, two-factor authentication options, domain-based visibility restrictions, and encrypted tagging for classification. GuardedBox targets organisations needing regulatory compliance support for frameworks such as GDPR, ENS, and ISO-27001, and is marketed toward use cases including password and credential management, audit firms, healthcare data exchange, and legal/notarial document sharing. The company describes over 20 years of experience in cybersecurity and DevSecOps methodology behind the product's development.
